What size mass would you put on a spring (k = 17.6 N/m) so it would oscillate with the same period as a 0.45 m long pendulum? (Use 9.81 m/s2 for g).

Report your answer:in terms of kg. Do not include units in your answer. They will be assumed to be kg.to a precision of hundredths of a kg. Use a format like #.## in your answer.to an accuracy of... more
